1. Have you ever heard of an ideal diode? If so, tell me what it is and when you would use it.
2. One of the approximations for a diode is the second approximation. Tell me what the equivalent circuit is and when a silicon diode conducts.
3. Draw the diode curve and explain the different parts of it.
If the primary voltage is 7967 V and the load impedance is ZL = 3.2 + j1.5Ω, what is the secondary voltage of the transformer? What is the voltage regulation of the transformer?
if Eb the energy per bit of a binary digital signal, is 10^-5 watt-sec and the one sided power spectral density of the white noise ,N0= 10^-6w/hz then what is the o/p SNR of matched filter.
a The cosmic background radiation has a temperature of 2.725 °K. At what wavelength is this radiation most intense b If the most intense radiation of a blackbody occurs at 1000 nm, what is its temperature
A very long insulating cylinder of charge of radius 2.30 cm carries a uniform linear density of 17.0 nC/m . If you put one probe of a voltmeter at the surface, how far from the surface must the other probe be placed so that the voltmeter reads 180..
Design a hardware implementation of a binary tree which functions as follows Each node of the binary tree has a unique address ( as discussed inclass). Given the address (A) of a node, and a datum (I), the machine willwrite I in node A.
A solar pond consists of a thin layer of fresh water floating ontop of a denser later of salt water. When the salty layer absorbssun light, it becomes hot, to 140 degrees C. The ambient temp isassumed to be 20 degrees C.
Given the following system of linear equations: x1 + 2x2 + x3 = 4, 12x1 + 16x3 = 28, 8x1 - x2 + 5x3 = 12(a) Write it in the form of Ax = b (b) Find all solutions to the system using Gauss elimination method
Given that, stator iron loss is 2kW, windage and friction losses are 1.2kW and resistance between two stator terminals = 0.4W, for slip s=0.05, mechanical power supplied to the load PL=41.5 kW and Motorefficiency h =82%; Calculate: Line current dra..
